Answer: 51
Step-by-step explanation:
let x be the number.
(70%)x = 42
0.7 x = 42
x = 60
we check 15% x 60 = 0.15 x 60 = 9, which is true.
85% of that number = 85% x 60 = 0.85 x 60 = 51.
Answer:
$13842.43
Step-by-step explanation:
Given data
Value of car=$15,250
Rate of depreciation= 16%
Time = 6 years
We can use the exponential function below to model the value of the car after 6 years
v(t)= a(r)^x
But r= 1-0.016----------Because the value is depreciating
a=15,250
r=0.016
x=6
Substitute
v(t)= 15250(1-0.016)^6
v(t)= 15250(0.984)^6
v(t)= 15250*0.9077
v(t)= $13842.43
Hence the value will be $13842.43 after 6 years
Answer:
(a) the interest is $6384
Hope this helps!
To solve this, plug in 8 for X
3+9(8-1) then solve
3+9(7)
3+63
66
I hope I've helped!
The second option. "Soil A has greater growth because It's data have a greater mean" I'm like 80% sure.
